Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery to prevent any electrical issues.

2. Check and Replenish Brake Fluid

Tools Required: Brake fluid, funnel, rags
Inspect the brake fluid reservoir for low levels.
If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Clean any spills with rags to avoid damage to paint.

3. Inspect and Repair Leaks

Tools Required: Wrench set, pliers, brake line repair kit (if necessary)
Inspect all brake lines and hoses for signs of wear or leaks.
Tighten any loose fittings and replace any damaged brake lines or hoses as necessary.
If leaks are found at calipers, replace the caliper or seals as required.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing
Begin with the brake furthest from the master cylinder (usually the rear passenger side).
Attach the clear tubing to the bleeder valve and submerge the other end in a container with brake fluid.
Open the bleeder valve and have an assistant press the brake pedal several times, holding it down on the last pump.
Close the bleeder valve and instruct the assistant to release the brake pedal.
Repeat until no air bubbles are present in the fluid.
Move to the next wheel and repeat until all brakes are bled.

5. Inspect Brake Components

Tools Required: Socket set, torque wrench
Remove the wheel to access the brake components.
Check the brake pads for thickness; replace if worn beyond specifications.
Inspect rotors for scoring or warping; resurface or replace as necessary.
Ensure calipers are functioning correctly and not seizing.
